The magnitude of the measured gamma interferon level cannot be correlated to stage or degree of infection, level of immune responsiveness, or likelihood for progression to active disease. of active, infectious tuberculosis might result in extensive transmission to highly susceptible populations. QFT is an interferon-gamma (IFN-) release assay, commonly known as an IGRA, and is a modern alternative to the tuberculin skin test (TST, PPD or Mantoux). These antigens elicit gamma interferon responses from TB-sensitized CD4+ T-helper lymphocytes. Refer to: Updated Guidelines for Using Interferon Gamma Release Assays to Detect Mycobacterium tuberculosis Infection--United States, 2010 (), for more information concerning test performance in low-prevalence populations and use in occupational screening.

Prior BCG (Bacille Calmette-Gurin) vaccination does not cause a false-positive IGRA test result. You are considered to have a low sperm count if you have fewer than 15 million sperm per milliliter or less than 39 million sperm total per ejaculate.
